Abstract:

Electricity supply as well as the provision of other forms of resources is one of the foundations of efficient agriculture. However, due to the reduction in the number of people living in rural settlements, there have been a large number of power lines with considerable lengths supplying small loads, hence resulting in an increase in power supply efficiency. A single-wire power transmission is an option for reducing the capital cost of power line construction by utilizing fewer conductors and fittings and lighter power transmission towers while lowering operational expenses.

Abstract:

Through intelligent resistivity tester and universal tensile testing machine, the physical properties of steel-cored aluminum strand above smoldering biomass fuel were analyzed. The results show that compared with the original aluminum single wire, the resistivity of each aluminum single wire under each biomass smoldering condition increases, and the increase amplitude increases with the decrease of the height of the aluminum single wire. The height of the steel core aluminum strand has no obvious effect on the tensile strength before and after smoldering. When the height of the steel-cored al

Abstract. In this contribution a concept of matching the termination of radiating non-uniform transmission-lines is proposed. Using Transmission-Line Super Theory, position and frequency dependent line parameters can be obtained. Therefore, a characteristic impedance can be determined which is also position and frequency dependent. For a single wire transmission-line it could be shown that the maximum value of that characteristic impedance is an optimal termination in the sense of minimizing the variation of the current on the line. This indicates that matching is not a local effect at the pos

Abstract - This paper presents the design and development of a Unified Power Quality Conditioner (UPQC) that converts 230V AC to 12V DC while operating within a Single Wire Earth Return (SWER) power distribution network. SWER is an economical and widely used method for delivering electricity in rural and remote areas using a single live wire and the earth as the return path. However, SWER systems are vulnerable to voltage instability, harmonics, and poor power quality due to long transmission distances and load imbalances. The proposed UPQC system integrates both series and shunt compensation

Abstract:

The article provides results of tests of a resonant single-wire power transmission system for induction heating of a switch rail in the organization of train traffic in difficult winter climatic conditions.Laboratory tests have shown the possibility and feasibility of applying heating by an induction method based on a resonant system for transmitting electricity at an increased frequency. Induction heating occurs in the metal due to the excitation of electric currents by an alternating electromagnetic field. With induction heating, only the conductive body is heated, and not the heating elemen

The article is concerned with a complex investigation of the influence of the plane wave coupling with a certain function of time, incident direction and polarization to a linearly loaded transmission line network comprised of three single-wire conductors with different lengths connected in the center. Line load is represented as 50 Ω resistors connected to all terminations of the transmission line network. The exemplary network was modeled on a computer and experimentally investigated in a gigahertz transverse electromagnetic GTEM cell, which allows creating an electromagnetic field of a cert

Abstract The worldwide first in-vacuum elliptical undulator, IVUE32, is being developed at Helmholtz-Zentrum Berlin. The 2.5 m long device with a period length of 3.2 cm and a minimum gap of about 7 mm is to be installed in the BESSY II storage ring. It will deliver radiation in the soft X-ray range to several beamlines. The proximity of the undulator structure to the electron beam makes the device susceptible to wakefield effects which can influence beam stability. A complete understanding of its impedance characteristics is required prior to installation and operation, as unforeseen heating

Quantum plasmonics opens the option to integrate complex quantum optical circuitry onto chip scale devices. In the past, often external light sources were used and nonclassical light was coupled in and out of plasmonic structures, such as hole arrays or waveguide structures. Another option to launch single plasmonic excitations is the coupling of single emitters in the direct proximity of, e.g., a silver or gold nanostructure. Here, we present our attempts to integrate the research of single emitters with wet-chemically grown silver nanowires. The emitters of choice are single organic dye mole

Abstract:

Optimizing the use of existing high-voltage transmission lines demands real-time condition monitoring to ensure structural integrity and continuous service. Operating these lines at the current capacity is limited by safety margins based on worst-case weather scenarios, as exceeding these margins risks bringing conductors dangerously close to the ground. The integration of optical fibers within modern transmission lines enables the use of Distributed Fiber Optic Sensing (DFOS) technology, with Chirped-Pulse Phase-Sensitive Optical Time-Domain Reflectometry (CP-ΦOTDR) proving especially effecti

Abstract Transmission of the electric power is accompanied with generation of low - frequency electromagnetic fields. Electromagnetic compatibility studies require that the fields from sources of electric power be well known. Unfortunately, many of these sources are not defined to the desired degree of accuracy.
